NEW YORK (MarketWatch) -- Shares of iBio
IBIO, -1.82%
soared 42% in active premarket trade Thursday, after the company said it has offered to assist the U.S. government by making its proprietary antibody production technology available to deal with the current Ebola virus outbreak. In response to shareholder and media inquiries, the company said the way it produces, in collaboration with Caliber Biotherapeutics, pharmaceutical proteins in plants has proven to have efficacy advantages over similar antibodies produced in Chinese hamster ovary cells. The stock has roughly quadrupled year to date through Wednesday, as the Ebola virus outbreak spread. On Thursday, a Air France aircraft flying from Paris was grounded in Madrid amid concerns one of the passengers onboard had Ebola.
